Hi devels, there are two issues concerning invoking optimizations: 1. this document: http://llvm.cs.uiuc.edu/docs/GettingStarted.html is very nice, it would be good though to add in a section An Example Using the LLVM Tool Chain examples on optimization step. 2. If i am not wrong there is no tool, which integrates all steps: llvmgcc->opt->llc into something like llcc (and

Yup, this is EXACTLY what is going on. I took this very simple C function: int Array[1000]; void test(int

Adam, I recant my previous message. I built FreeType with GCC not LLVMGCC by accident (I shoulda checked!). The thing is, FreeType's makefiles don't respect environment variables. So, I did this: CC=/path/to/llvmgcc CXX=/path/to/llvmg++ configure make and was able to reproduce the problem. Not sure what's up with that but as Misha pointed out, llvmgcc isn't any

Hi llvmer, I am trying to learn how to use llvm. My question is described as the following, there has already a testcase code, and I get bytecode by using llvmgcc. What I want to do is to insert a call funcation into each basic block, which is for statistic some information. 1) I implement call function in another c/cpp file and can I insert the external call function to existed bytecode ? if it

Many of you are probably wondering about the status of the 2.3 release. Unfortunately, this release has been very difficult and the list of regressions very high. The list has finally dwindled down to the following regressions: Linux/x86: SingleSource/Benchmarks/CoyoteBench/fftbench [ JIT Codegen, JIT] MultiSource/Applications/minisat/minisat [CBE] Darwin/x86:

I'll test on Darwin/PPC, precompiled llvmgcc, objdir == srcdir.

I haven't seen anyone claim x86 linux objdir == srcdir, so I'll test it out. Missed the 18th,but I'll try to have it done asap. On Apr 18, 2006, at 2:51 PM, Robert L.

Hi, I would like to use LLVM-GCC to compare its performance with other compilers. Something like testsuite "Computing very large Fibonacci numbers" at http://article.gmane.org/gmane.comp.lang.c%2B%2B.perfometer/37.
